Here is the second guide on how to format the MicroSD in 2 partitions:
This, in comparison with the other guide is faster and easier, because the commands to run are few but obviously need to have a firmware with root permissions enabled.
Then let us go into the program and launch the Terminal Emulator commands:
$ su # cd/data # wget http://126.96.36.199/bin/lib/droid/sdsplit # chmod 555 sdsplit # ./fs-na sdsplit-1500M
Dollar and gates should not be written of course.
After a short time and written a lot :P we will have our SD partitioned and ready to load applications.
